2007-06-07[TCP]: Honour sk_bound_dev_if in tcp_v4_send_ackPatrick McHardy
A time_wait socket inherits sk_bound_dev_if from the original socket, but it is not used when sending ACK packets using ip_send_reply. Fix by passing the oif to ip_send_reply in struct ip_reply_arg and use it for output routing. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-25[IPV4]: Consolidate common SNMP codeHerbert Xu
This patch moves the SNMP code shared between IPv4/IPv6 from proc.c into net/ipv4/af_inet.c. This makes sense because these functions aren't specific to /proc. As a result we can again skip proc.o if /proc is disabled. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Acked-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S.

2007-04-25[IP]: Introduce ip_hdrlen()Arnaldo Carvalho de Melo
For the common sequence "skb->nh.iph->ihl * 4", removing a good number of open coded skb->nh.iph uses, now to go after the rest... Just out of curiosity, here are the idioms found to get the same result: skb->nh.iph->ihl << 2 skb->nh.iph->ihl<<2 skb->nh.iph->ihl * 4 skb->nh.iph->ihl*4 (skb->nh.iph)->ihl * sizeof(u32) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S.

2007-01-26[TCP]: Restore SKB socket owner setting in tcp_transmit_skb().David S. Miller
Revert 931731123a103cfb3f70ac4b7abfc71d94ba1f03 We can't elide the skb_set_owner_w() here because things like certain netfilter targets (such as owner MATCH) need a socket to be set on the SKB for correct operation. Thanks to Jan Engelhardt and other netfilter list members for pointing this out. Signed-off-by: David S. Miller <davem@davemloft.net>

2006-12-02[TCP]: Don't set SKB owner in tcp_transmit_skb().David S. Miller
The data itself is already charged to the SKB, doing the skb_set_owner_w() just generates a lot of noise and extra atomics we don't really need. Lmbench improvements on lat_tcp are minimal: before: TCP latency using localhost: 23.2701 microseconds TCP latency using localhost: 23.1994 microseconds TCP latency using localhost: 23.2257 microseconds after: TCP latency using localhost: 22.8380 microseconds TCP latency using localhost: 22.9465 microseconds TCP latency using localhost: 22.8462 microseconds Signed-off-by: David S.

2006-04-09[NETFILTER]: Fix fragmentation issues with bridge netfilterPatrick McHardy
The conntrack code doesn't do re-fragmentation of defragmented packets anymore but relies on fragmentation in the IP layer. Purely bridged packets don't pass through the IP layer, so the bridge netfilter code needs to take care of fragmentation itself.

2006-03-20[NET]: {get|set}sockopt compatibility layerDmitry Mishin

2006-02-15[XFRM]: Fix SNAT-related crash in xfrm4_output_finishPatrick McHardy
When a packet matching an IPsec policy is SNATed so it doesn't match any policy anymore it looses its xfrm bundle, which makes xfrm4_output_finish crash because of a NULL pointer dereference. This patch directs these packets to the original output path instead. Since the packets have already passed the POST_ROUTING hook, but need to start at the beginning of the original output path which includes another POST_ROUTING invocation, a flag is added to the IPCB to indicate that the packet was rerouted and doesn't need to pass the POST_ROUTING hook again.

2006-01-07[NETFILTER]: Fix xfrm lookup in ip_route_me_harder/ip6_route_me_harderPatrick McHardy
ip_route_me_harder doesn't use the port numbers of the xfrm lookup and uses ip_route_input for non-local addresses which doesn't do a xfrm lookup, ip6_route_me_harder doesn't do a xfrm lookup at all. Use xfrm_decode_session and do the lookup manually, make sure both only do the lookup if the packet hasn't been transformed already. Makeing sure the lookup only happens once needs a new field in the IP6CB, which exceeds the size of skb->cb. The size of skb->cb is increased to 48b. Apparently the IPv6 mobile extensions need some more room anyway. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-01-07[IPV4]: reset IPCB flags when neccessaryPatrick McHardy
Reset IPSKB_XFRM_TUNNEL_SIZE flags in ipip and ip_gre hard_start_xmit function before the packet reenters IP. This is neccessary so the encapsulated packets are checked not to be oversized in xfrm4_output.c again. Reset all flags in sit when a packet changes its address family. Also remove some obsolete IPSKB flags. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-01-05[NETFILTER]: Call POST_ROUTING hook before fragmentationPatrick McHardy
Call POST_ROUTING hook before fragmentation to get rid of the okfn use in ip_refrag and save the useless fragmentation/defragmentation step when NAT is used. The patch introduces one user-visible change, the POSTROUTING chain in the mangle table gets entire packets, not fragments, which should simplify use of the MARK and CLASSIFY targets for queueing as a nice side-effect.

2006-01-03[INET_SOCK]: Move struct inet_sock & helper functions to net/inet_sock.hArnaldo Carvalho de Melo

2006-01-03[IPV4]: Safer reassemblyHerbert Xu
Another spin of Herbert Xu's "safer ip reassembly" patch for 2.6.16. (The original patch is here: http://marc.theaimsgroup.com/?l=linux-netdev&m=112281936522415&w=2 and my only contribution is to have tested it.) This patch (optionally) does additional checks before accepting IP fragments, which can greatly reduce the possibility of reassembling fragments which originated from different IP datagrams.

2005-08-29[NET]: Kill skb->real_devDavid S. Miller

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
